CUDA_V12_app
Sutaru Tsureku:
Franz, this is a known BUG of the opt._CUDA_app.
Raistmer inserted a BUG detection, which should detect and display the BUG of the CUDA BUG.
Sometimes it fail and show this 'funny/strange' output.
Normally it should display the -12 error with BUG report.
But it show sometimes (very rarely) an 'Out Of Memory' error.
Raistmer, you can't remember, we both together found/discovered this.. ;)
You should not have enabled SLI for CUDA. The new driver should disable SLI automatically if CUDA.
Raistmer, in the SETI@home forum I saw a member also with Win7.
He have 2x GTX295 and ALL GPUs had only ~ 400 or ~ 200 MB free GPU RAM before CUDA load.
Sometimes too less and then the CUDA WU was crunched on CPU (falling back to CPU processing...).
I guess it's a Win7 or nVIDIA_driver BUG.
Sutaru Tsureku:
Franz, BTW.
This Win7 PC have very much 1 errors.
It's like the other member I helped with his Win7 and 2x GTX295 PC.
Also Fred said, he couldn't let run well CUDA on his Win7 and 2x GTX295.
Not 190.x , 191.x and not 195.x . He continue with WinXP.
So I recommended the member to install WinXP and since then no error.
It could be a BUG in Win7 or the current available nVIDIA_drivers.
So the time will tell if with a new nVIDIA_driver it will be better.
The easiest would be to install WinXP. ;)

Ah, good that you remind me. Yes, sometimes memories fall :)

i am using W7 on my machine with 9600GT and 8500GT for 4 monts with always latest drivers (beta or not) and NEVER had problems low mem on any CUDA project
